Multi-scale Modeling: from Electromagnetism to Grid

The numerical electromagnetic tools for complex structures simulation, i.e. multi-scale, are often limited by available computation resources. Nowadays, Grid computing has emerged as an important new field, based on shared distributed computing resources of Universities and laboratories. Using these shared resources, this study is focusing on grid computing potential for electromagnetic simulation of multi-scale structure. Since the numerical simulations tools codes are not initially written for distributed environment, the first step consists to adapt and deploy them in Grid computing environment. A performance study is then realized in order to evaluate the efficiency of execution on the test-bed infrastructure. New approaches for distributing the electromagnetic computations on the grid are presented and validated. These approaches allow a very remarkable simulation time reduction for multi-scale structures and friendly-user interfaces
